Changing Percent to Decimal

The question reads,
"In a survey of 270 grade 9 students, 58 percent liked rock music.
How many did not like rock music?"
I have tried to figure it out by making the 58 percent into a
decimal (.58). Is that right?

Yes, that will work. Here's one way to do this problem:
.58 * 270 = number who like rock music
270 - number who liked rock music = number who DID NOT like rock
music.
Does this make sense?
